Answer:

x=-12

Step-by-step explanation:

x^2-24x+144=0

When you see it as =0, that doesn't mean it's 0. it means it needs more deep solving.

x^2+24x+144-144=0-144

x^2+24x=-144

x^2+24x+12^2=-144+12^2

x^2+24x+12^2=0

(x+12)^2=0

x+12=0

x=-12

Len [333]

Y= 10 + 1.25x
This is the answer because 10 is the initial fee (you start with it) and 1.25 is added for each minute, with each minute being the variable

The density of a certain material is such that it weighs 71 pounds for every 2.5 gallons of volume. Express this density in tons

kvasek [131]

Answer:

$d=3.75\ \text{tons per cubic meter}$

Step-by-step explanation:

Given that,

Mass of a certain material, m = 71 pounds

Since, 1 ton = 2000 pounds

71 pounds = 0.0355 ton

Volume of the material, V = 2.5 gallons

Since, 1 m³ = 264.172 gallon

2.5 gallon = (2.5/264.172 ) m³

Density,

$d=\dfrac{m}{V}\\\\d=\dfrac{0.0355\ \text{tons}}{\dfrac{2.5}{264.172}\ m^3}\\\\d=3.75\ \text{tons per cubic meter}$
